(a) flowing liquid into a glass container (12, 12', 112, 212, 312, 412, 512, 612, 712) having a neck (18, 18', 118, 218, 318, 418, 518); and
(b) non-removably coupling an anti-refill fitment (14, 414, 514, 614, 714) to the neck of the glass container via an attachment ring (16, 16', 116, 216, 316, 416, 516, 616, 716) to render the product tamper-evident, wherein the attachment ring is adapted to indicate opening of the container by irreversibly changing color due to exposure to air such that the change is visible from outside of the glass container.

Description

The present disclosure is directed to containers and, more particularly, to container attachments.

Background and Summary of the Disclosure

Many containers are provided with tamper-resistant devices to resist refilling of contents in the containers. For example, a beverage container can include a fitment that renders the container non-refillable, so as to impede efforts to refill the container with inferior products. U.S. Patent 3,399,811 illustrates a container of this type.
A non-refillable closure for a bottle is known from US 1,994,625 , which includes a conical valve element. A grooveway registers with a grooveway in the neck and a split spring ring springs into the groove of the neck to interlock a skirt and the neck of the bottle together.
US 4,511,052 shows a container assembly incorporating a chemical indicator normally hermetically sealed from the ambient atmosphere upon opening of the container assembly.
Improvements in anti-fraud bottles and other containers are known from GB 2391 A.D. 1911. Within the bottle neck are recesses such that when springs are sufficiently inserted the springs cannot be withdrawn without breaking the glass cap.
A general object of the present disclosure, in accordance with one aspect of the disclosure, is to provide a method of producing a product with a liquid in a container including an attachment ring for the container that may be used as an anchor to non-removably secure a fitment to the container, as a use-evident indicator carried by the container to indicate that the container has been opened and/or that original liquid product has been dispensed from the container, and/or as a tamper-indicator to evidence efforts to tamper with the package via breakage of the container.
The present disclosure embodies a number of aspects that can be implemented separately from or in combination with each other.
A product in accordance with one aspect of the disclosure includes a container including a neck having an interior passage, and a ring non-removably coupled to the container neck.
In accordance with another aspect of the disclosure, there is provided a method of producing a product that includes (a) flowing liquid into a container having a neck, and (b) non-removably coupling a fitment into the neck of the container via an attachment ring to render the product tamper-evident.

Detailed Description of Preferred Embodiments

FIG. 1 illustrates a package 10 in accordance with an illustrative embodiment of the disclosure as including a container 12 to hold an original product therein, a closure 13 to close the container 12, a dispensing fitment 14 coupled to the container 12 for non-refillable dispensing of the product out of the container 12, and a ring 16 attached to the container 12 for one or more purposes. For example, and as will be described in further detail below, the ring 16 may be used as a fitment anchor or coupler to attach the fitment 14 to the container 12, as a use-evident indicator for indicating that the container 12 has been opened and/or that the product has been dispensed from the container 12, and/or as a tamper-indicator for evidencing efforts to tamper with the package 10. Although not illustrated, the package 10 also may include any suitable seals between the fitment 14 and the container 12, and/or at least a portion of the fitment 14 may be interference fit within the container 12 for integral sealing therebetween.
The container 12 may be, for example, a jug, a jar, or a bottle, for instance, a wine or spirits bottle, or any other suitable type of food or beverage container, and may be composed of glass or ceramic, or any other suitable material(s). The original product may include beer, wine, liquor, soda, other beverage, or any other suitable liquid, or food. Although not illustrated in the drawings, the container 12 may include a bottom or base, a body that may extend in a direction axially away from the base along a central longitudinal axis A, a shoulder extending in a direction axially away from the body, and a neck 18 extending in a direction axially away from the shoulder and including a neck finish 20. As used herein, directional words such as top, bottom, upper, lower, radial, circumferential, lateral, longitudinal, transverse, vertical, horizontal, and the like are employed by way of description and not limitation. Although not shown, the neck finish 20 may include one or more closure engagement elements, for example, helical threads, capping flange, and/or any other suitable feature(s), for coupling of the closure 13 to the container 12.
The container neck 18 may include an interior passage 22 to carry the fitment 14 and to communicate liquid out of the container body and through and out of the neck 18. The passage 22 may include a radially inner surface 24, and an internal annular recess 26 in the inner surface 24 for receiving at least a portion of the ring 16. The interior passage 22 may be of cylindrical shape or of any other suitable geometry. The recess 26 may be a circumferentially continuous groove that may be rectangular in transverse cross section, per the illustrated embodiment of FIG. 1, or may be of any other suitable shape and configuration.
The closure 13 may include a cover, for example, a metal foil, plastic cup, wax seal, or any other suitable cover. Although not illustrated in the drawings, in other embodiments, the closure 13 also or instead may include a threaded closure, crown closure, or the like, or a cork, plug, or any other suitable closure. In the latter embodiments, artisans of ordinary skill will recognize that the fitment 14 would be located further down into the container neck 18 to accommodate such an internal closure.
The fitment 14 may include a first end 28, a second end 30 disposed axially oppositely of the first end 28, and an axially extending circumferential outer wall 32 that may be disposed between the ends 28, 30 and in contact with the interior surface 24 in the passage 22 of the container 12. The outer wall 32 may be of cylindrical shape, or of any other suitable shape corresponding to the shape of the interior surface 24 of the container neck 18. The fitment 14 also may include an external annular recess 34 in the outer wall 32 corresponding to the internal annular recess 26 of the container 12 and for receiving at least a portion of the ring 16. Accordingly, the fitment recess 34 may be axially aligned with and overlapping the container recess 26. The fitment recess 34 may be a circumferentially continuous groove that may be rectangular in transverse cross section, per the illustrated embodiment of FIG. 1, or may be of any other suitable shape and configuration. As used herein, the term transverse may mean disposed at some non-zero angle with respect to the longitudinal axis A of the container 12 and along any direction intersecting the container 12 and may include but is not limited to a radial direction. The fitment 14 also may include a chamfer 36 between the first end 28 and the outer wall 32. Various features of the fitment 14 illustrated in the drawing figures are illustrative only, and may be of any other suitable type or construction.
The fitment 14 further may include any suitable features to impede or prevent refilling of the container 12. For example, the fitment 14 may include a check valve 38 that may be carried within the outer wall 32. The check valve 38 may include a check ball 40 and a valve seat 42, and/or any other suitable elements to permit flow of product out of the container 12 but prevent or retard flow of product into the container 12. Non-refillable fitments are well known to those of ordinary skill in the art, and any suitable type of non-refillable fitment may be used, whether a check valve type of fitment, an air trap type of fitment, or any other suitable type of refill-resistant fitment.
The fitment 14 may be non-removably secured to the container 12. The terminology "non-removably secured" includes a manner in which the fitment 14 is, by design-intent, not intended to be removed from the container 12 without damaging the container 12 and/or the fitment 14, or otherwise visibly compromising the structural and/or functional integrity of either or both. Also, the fitment 14 may render the container 12 non-refillable. In other words, the fitment 14 may prevent or at least impede efforts to refill the container 12, for example, with counterfeit products. The terminology "non-refillable" is used interchangeably herein with the terms refill-resistant and anti-refill, and includes a characteristic of the fitment 14 which, by design intent, is not intended to be refilled without damaging the container 12 and/or fitment 14 or otherwise visibly compromising the structural and/or functional integrity of either or both.
The ring 16 is at least partially radially disposed in the container recess 26 and in the fitment recess 34 so as to radially overlap both the container 12 and the fitment 14 to secure the fitment 14 to the container 12. More specifically, the ring 16 may be axially trapped by corresponding axially facing shoulders of the container 12 and the fitment 14 located adjacent the corresponding recesses 26, 34. The ring 16 may be rectangular in transverse cross section, as illustrated in FIG. 1, or may of any other suitable shape. The ring 16 may be composed of glass, metal, or any other suitable material. For instance, the ring 16 may be composed of a ferrous metal, for instance, iron or steel, to facilitate separation (via magnets or the like) of the ring 16 from container material during recycling. In other embodiments, the ring 16 may be composed of aluminum, copper, titanium, stainless steel, or non-metal.
In the embodiment illustrated in FIGS. 1 and 2, the ring 16 may be a split ring, in other words, extending less than 360 angular degrees such that the ring 16 includes circumferential ends 17 (FIG. 2). Accordingly, the ring 16 may be resilient or spring-like, such that a radial force may be imposed on the ring 16 to radially inwardly deflect the ring 16 from a rest state toward a radially compressed state, but wherein the ring 16 returns toward its rest state upon removal of the force. Accordingly, the ring 16 may be radially resiliently compressible, for example, to facilitate assembly of the ring 16 to the container 12 and to facilitate assembly of the fitment 14 to the container 12.
The resilient ring 16 is illustrated in a rest state, but when the fitment 14 is assembled to the container 12, the resilient ring 16 is compressible in a radially inward direction to a compressed state to allow the fitment 14 to be inserted into the container neck 18. For example, the ring 16 may be C-shaped or semi-circumferential, having circumferential ends, circumferentially spaced apart from one another. The ring 16 may include an annular chamfer 35 to facilitate insertion of the fitment 14 into the container neck 18 under a force greater than that supplied by the weight of the fitment 14 alone. The ring 16 is resiliently expandable from the compressed state back to the rest state when the ring 16 axially traverses or clears an internal feature of the container 12. For example, the ring 16 may axially clear the internal surface 24 of the neck 18 and expand resiliently back to its rest state into the groove 26 where a trailing surface or edge 37 of the ring 16 is engageable with an axially facing shoulder of the container 12, for example, at an axial side of the groove 26. At that point, the fitment 14 becomes non-removably secured within the container 12.
In production of the container 12, the recess 26 may be produced by forming or machining. In one embodiment, the recess 26 may be formed during blank molding or blow molding of the container 12. For example, the recess 26 may be formed by a blank mold or finish mold plunger having an expandable annular portion. During blank forming or finish forming, the plunger would extend into a blank or container neck, the expandable annular portion of the plunger would expand radially outwardly to form the recess 26, and then the expandable annular portion would retract radially inwardly to allow retraction of the plunger. Then, the container 12 may be annealed and, thereafter, the ring 16 may be assembled into the formed recess 26.
In another embodiment, the ring 16 may be coupled to the container 12 during molding of the container 12 or after the container 12 is molded. For example, the ring 16 may be insert-molded within a blank mold or a blow mold of a container manufacturing process.
In a further embodiment, after forming of the container 12, the container neck 18 may be machined to produce the recess 26, for example, via grinding, milling, turning, or the like. More specifically, a milling cutter or trepan tool may be inserted into the container neck 18 and spun at high velocity to remove material of the container neck 18 to define the recess 26. Accordingly, the recess 26 would be well-defined and would accommodate assembly of the ring 16 thereto after machining. In this embodiment, the machined recess 26 may require stress relieving via heat treatment before assembly of the ring 16 to avoid weakness in the region of the recess 26.
Referring again to FIG. 1, during packaging, the original product may be flowed into the container 12 in any suitable manner, and then the fitment 14 may be coupled into the neck 18 of the container 12 via the ring 16 to render the package 10 tamper-evident. For example, the ring 16 may be compressed radially until its radially outer diameter is smaller than the radially inner diameter of the passage 22 of the container neck 18, and then the ring 16 may be inserted into the passage 22 of the container neck 18 and into axial alignment with the container recess 26. Thereafter, the ring 16 may be released to allow the ring 16 to expand into the container recess 26. Next, the fitment 14 may be inserted into the passage 22 of the container neck 18 wherein the fitment chamfer 36 engages a radially inner surface or edge of the ring 16 and continued insertion of the fitment 14 causes radially outward displacement or expansion of the ring 16. Finally, when the fitment 14 has been inserted such that the external recess 34 axially aligns with the internal annular recess 26 of the container 12, the ring 16 snaps back or expands back toward its rest state and radially overlaps the recesses 26, 34 to axially restrain the fitment 14 relative to the container 12. The engagement between the ring 16 and the container 12 and the fitment 14 is such that the fitment 14 cannot be removed without causing visible damage to the container 12 and/or to the fitment 14.
Although the groove 26 is illustrated as an example of the container internal feature, any other suitable internal feature(s) could be used. For example, the ring 16 could be retained axially between axially spaced internal embossments or shoulders of the container neck 18, by separate components installed in the neck 18, or by any other suitable feature(s) to retain the ring 16. More specifically, the ring 16 may be coupled between radially inwardly extending portions of the container neck 18.
As illustrated in FIG. 1A, for example, a package 10' may include a container 12', which may be formed to include a first annular detent 25' extending radially inwardly from an inner surface 24' of a container neck 18'. The container 12' also may be formed to include a second annular detent 27' spaced axially from the first annular detent 25' and which may establish a groove 26' therebetween. In any case, the fitment 30 carrying the ring 16' may be inserted into a neck 18' of the container 12', wherein the ring 16' may be compressed radially inwardly, until the ring 16' snaps past the first annular detent 25' and into the groove 26'. At that point, the ring 16' may relax or be uncompressed wherein the ring 16' is axially trapped between the detents 25', 27'.
FIG. 3 illustrates another illustrative embodiment of a package 110 including a container 112 and a ring 116 non-removably coupled to the container 112. This embodiment is similar in many respects to the embodiment of FIGS. 1-2 and like numerals between the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another. Additionally, the description of the common subject matter generally may not be repeated here.
The indicator ring 116 may be the same as or similar to an indicator disclosed and shown in U.S. Patent Application 13/832,589 filed March 15, 2013 (Attorney Docket 19205 and entitled CONTAINER HAVING A USE INDICATOR), which was filed on the same date as the present application and is assigned to the assignee hereof and is incorporated herein by reference in its entirety.
The container 112 includes a neck 118 and an internal annular recess 126 for receiving the ring 116. In this embodiment the ring 116 may be in diametric contact with the container 112 within the recess 126. The ring 116 may facilitate evidencing of efforts to tamper with the package 110, for example, via breakage of the container 112 when someone attempts to remove or defeat a non-refillable fitment and refill the container 112. In this regard, and although not shown, the package 110 also may include a fitment that may be inserted into the container neck 118 and non-removably secured thereto, for example, by being snap fit to the ring 116 in any suitable manner. For example, the fitment may be inserted into the container neck 118 wherein a fitment chamfer engages a radially inner surface or edge of the ring 116 and continued insertion of the fitment causes radially inward displacement or contraction of a resiliently radially compressible portion of the fitment. As used herein, the terminology "snap fit" includes abrupt engagement of two members (with or without audible or tactile feedback) via spring-like or resilient deflection of at least a portion of one of the members and, once installed, the deflected portion may return to or toward its original shape. When the fitment has been inserted such that an external annular recess axially aligns with an internal annular recess of the container 112, the compressible portion of the fitment snaps back or expands back toward its rest state such that one or more axially facing shoulders of the fitment engage against the ring 116 to axially restrain the fitment relative to the container 112 so that the fitment cannot be removed without causing visible damage to the container 112.
The ring 116 may function as a heat concentrator, wherein the ring 116 may be composed of a material that expands at a faster rate and to a greater degree than the material of the container 112. For example, the ring 116 may be composed of metal, for instance, steel, when the container 112 is composed of glass or ceramic. Then, if counterfeiters attempt to melt a plastic portion of the fitment by applying heat to the fitment, the ring 116 will expand radially and axially and, thus, break the container neck 118, thereby facilitating evidence of tampering with the container 112 and likely rendering the container 112 unusable. In this embodiment, the container 112 would break because the ring 116 expands radially and/or axially to a greater extent than a corresponding portion of the container 112 for a given temperature and, thus, the expanding ring 116 would stress the container 112 beyond its breaking point.
Furthermore, an outer surface of the ring 116 may carry indicia 150, for example, brand name indicia, package serial number indicia, a logo, a slogan, or the like. The indicia 150 may be recessed in a radially outer surface of the ring 116 wherein the indicia 150 may be formed, machined, lasered, etched, or produced in any other suitable manner. Accordingly, the indicia 150 are positioned on the inside of the container 112 but are visible therethrough.
Moreover, the ring 116 may evidence opening or dispensing of original product from the container 112 for example, via a state change of the ring 116 after the package 110 has been opened and/or original product has been dispensed from the container 112. The ring 116 may be of any suitable composition(s) and constructed in any suitable manner to enable the ring 116 to exhibit different visual characteristics. For example, the ring 116 may be composed of a base material, and an oxidizable coating carried by the base material. The base material may include a metal, and the coating may include a reactive material that reacts with any one or more of the constituents of air so as to visibly change appearance of the material. For example, the air-reactive material may include an oxygen-reactive material or a nitrogen-reactive material. More specifically, the air-reactive material may include oxygen-reactive metals, polymers, or dyes. For instance, the air-reactive material may include copper, iron, potassium, sodium, PEN (polyethylene naphthalate), polycarbonate, or one or more flavonoids, for example, flavanones, flavanoles and dihydrochalcones, chalcones, aurones, or anthocyanidins, depending on the reaction and desired color.
During product packaging, the ring 116 may be assembled to the container 112 in an inert environment in any suitable manner, and the closure 13 may be sealingly applied to the container 112 to prevent oxidation of the ring 116. Accordingly, in the sealed package 110, the ring 116 may exhibit a first visual characteristic, for example, a first color.
But, referring now to FIG. 4, upon contact with air, for example, when the package 110 is opened, the ring 116 is adapted irreversibly to change a characteristic of the ring 116 that is visible from outside of the container 112 to advise a user that the package 110 has been opened. Accordingly, the ring 116 will exhibit the second visual characteristic different from the first visual characteristic. For example, the ring 116 is illustrated in FIG. 4 in a state different from that shown in FIG. 3. In particular, the ring 116 may be a different color after the package 110 has been opened.
Therefore, the ring 116 may provide a security feature. The package 110 may be opened and, thereafter, if counterfeiters attempt to refill the emptied container 112 with counterfeit liquid product and repackage the package 110 with a closure, the refilled and repackaged package will include the state changed ring 116 as evidence of product refilling and repackaging. In other words, the package 110 is permanently or irreversibly identifiable as being a once-fillable package. Over time, purchasers will become educated to spot refilled counterfeit packages. Thus, counterfeiters will be deterred from offering counterfeit packages to such educated purchasers.
FIG. 5 illustrates another illustrative embodiment of a package 210 including a container 212 and a ring 216 non-removably coupled to the container 212. This embodiment is similar in many respects to the embodiment of FIGS. 1-4 and like numerals between the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another. Additionally, the description of the common subject matter generally may not be repeated here.
The container 212 includes a neck 218 and an interior surface 224 for receiving the ring 216. In this embodiment, however, the ring 216 may be circumferentially continuous and coupled to the surface 224 with a bonding material 260 between an outer surface of the ring 216 and a corresponding inner portion of the interior surface 224. The ring 216 also may carry indicia 250. The bonding material 260 may include room temperature vulcanizing (RTV) silicone, heat-activated ceramic or glass bonding compound, a solder glass, a ring of soda lime glass, an adhesive, an epoxy, or a sol-gel adhesive, or the like.
This embodiment is particularly adapted for use with a ceramic or glass ring 216 that may not be easily attachable to the containers of the previous embodiments.
FIGS. 6 and 7 illustrate another illustrative embodiment of a package 310 including a container 312 and an attachment ring 316 non-removably coupled to the container 312. This embodiment is similar in many respects to the embodiment of FIGS. 1-5 and like numerals between the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another. Additionally, the description of the common subject matter generally may not be repeated here.
Referring now to FIG. 6, the container 312 includes an annular relief 326 to receive the attachment ring 316. The annular relief 326 may be established by a radially outwardly extending bulge 318a, which may be formed in the wall of the container neck 318 and may have an internal diameter larger than that of axially adjacent portions of an internal surface 324 of the container neck 318. The bulge 318a may be formed during forming of a blank or parison for the container 312 and/or during forming of the container 312 itself. In other embodiments, the annular relief 326 may be a machined groove or a formed groove, or a space between radially inwardly projecting portions of the container neck 318.
In any case, the attachment ring 316 includes a substrate 316a and a coating 316b carried by the substrate 316a. The substrate 316a may include a metal and the coating may include a polymer. In one example, the metal may include stainless steel, and the polymer may include polyethylene, polypropylene, and/or any other suitable material.
In one embodiment, the attachment ring 316 may be C-shaped and may be assembled to the container 312 by radially compressing the ring 316 and inserting the ring 316 into the container neck 318 until the ring 316 is axially aligned with the relief 326. At that point, the ring 316 is allowed to expand into registration with the relief 326 in contact with the container neck 318.
In another embodiment, the attachment ring 316 may be assembled to the container 312 using a shrink fit. For example, the ring 316 may be frozen to reduce the diameter of the ring 316, and inserted into the container neck 318 until the ring 316 is axially aligned with the relief 326. At that point, the ring 316 may be warmed, or allowed to warm, to expand into registration with the relief 326 in contact with the container neck 318.
Referring now to FIG. 7, the ring 316 may be C-shaped, having circumferential ends 317 spaced apart circumferentially. In other embodiments, the ring 316 may be circumferentially continuous.
In any case, if a counterfeiter attempts to apply heat to the attachment ring 316, for example, in an effort to melt the ring 316 and an anti-refill fitment (not shown), the metal ring 316 will expand at a faster rate and to a larger degree relative to the glass wall of the neck 318. Such expansion of the metal ring 316 will crack or otherwise break the container neck 318, thereby providing an indication or evidence of tampering with the container 312.
